The definition of antioxidants is relatively new and refers to a group of substances found mainly in plants that can inhibit or prevent damage to human cells and tissues.
The definition of "Antioxidants "was given in 1995 by Halliwell and Gutteridge.
The role of antioxidants is to minimize cell and tissue damage typical of existing metabolic processes.
- Antioxidants are divided into several groups.
- The food industry uses artificial antioxidants to preserve food. Studies indicate potential damage to synthetic antioxidants.
Oxidation reactions produce free radicals (toxins) that can start multiple chain reactions that eventually cause cell damage or death.
- Antioxidants remove these free-radicals either by oxidizing them or by inhibiting other oxidative reactions. Thus, harmful chain reactions are prevented.
- Due to the lack of appropriate nutrition and exercise, air pollution, smoking, etc., oxidative stress is an integral part of many human diseases; this stress leads to lethal diseases such as cancer. Therefore, antioxidants must be included in your diet.
- Synthetically produced antioxidants are currently used in the food industry to prolong product shelf-life; there is a developing trend to eat ample, available, efficient natural antioxidants to minimize cell damage.
- There are two major groups of antioxidants in living cells:
- Enzymatic antioxidants.
- Non-enzymatic antioxidants.
- There are many antioxidants in the form of supplements that promise miracles. They are always inferior to natural foods containing potent antioxidants such as berries (all kinds). Regular consumption of natural antioxidants boosts the immune system.
Glutathione - Essential antioxidant at the cellular level. (Often ignored.)
- Glutathione is of enormous importance in the proper functioning of the immune system.
- Severe and prolonged glutathione deficiency can cause serious illnesses, including cancer.
- Glutathione cannot be consumed in its active form; the liver must synthesize its active form. (There are glutathione injections on the market, their effectiveness is unclear.)
- Eating sulfur-rich foods has a significant ability to improve the level of glutathione in the body:
- Such as Avocado, cabbage, cauliflower, kale, broccoli, onion, garlic.
